The Helly Hansen Adventure Challenge Series is gearing up for another successful season.

This year, there are four UK events, where each one-day race can be entered individually or as a series. Blending physical challenge and teamwork, they are designed for teams of three who must stay together throughout the race. Each adventure race features a three way mix of trail running (10k), challenging mountain biking (25k) and canoeing on flat water in an inflatable kayak (1.5k). The fastest teams are likely to complete the course in under three hours, with most coming in within five hours and a pooped few crossing the line in seven hours.

This year's events will be held on: Sunday 19th October: Longmoor Camp, Hampshire - Weavers Down Autumn Assault Sunday 7th December: Hawley, Near Camberley, Surrey - Hawley Winter Wonder Sunday 1st February 2009: Pirbright, Surrey - Porridgepot Or Bust! Sunday 29th March 2009: Windermere, Lake District - Cumbrian Commotion

Better get training!
